SAW GUIDE.

v Application filed August 6, 1921. Serial 110,490,271.

To all whom it may concern.'

Be it known that I, BnNmn Gr. MYRAN,

a citizen of the United States, residing at Sand Creek, in the county ofDunn and State of Visconsin, have invented new and useful Improvementsin Saw Guides, of which the following is a specification. This inventionrelates to saw mill appliances, particularly to saw guides, and has forits object the provision of a novel device adapted for association witha rotary saw, the parts of the device being readily adjustable in everyway whereby to effect the proper guiding action. I

An important object is the provision of a device of this `characterwhich is provided with novel means for adjusting a pair of guides whichare located at the outside and inside of the saw, the adjusting meanspermitting guide pins to be spaced Yat any desired distance from thesaw.

Another object is the provision of a device of this character which isprovided with novel means whereby to positively lock or jam the guidemembers so that displacement thereof will be prevented under allcircumstances. l

A further object is the provision of a device of this character whichwill be very safe for the operator inasmuch as heV does not have toleave his position to V'make the necessary adjustment and does not haveto rotating saw, it being well known thatfit frequently occurs that asawyer has a hand cut off while performing the necessary adjustment andmanipulations aroundv the saw.

Still another object is the provision of a device of this character inwhich the guide members are themselves effectively guided by supportingyokes, means being provided for regulating the frictionon the guidemembers so that they may be moved `with more or less readiness and maynot more too easily. v

An additional object is the provision of a device of this characterwhich will be simple and inexpensive in manufacture, highly eficient inuse, durable in service and a .general improvement in the art.

ith the above and other objects and advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings inwhich, Y

Figure 1 is a plan Viewl of my device.

Figure 2 is a side elevation thereof.l Figure 3 is afront elevation withparts in section.

Figure 4 is a sectional view on the line 4 4 of Figure 1.

Figure 5 is a sectional view on the line 5 5 of Figure 1.

Figure 6 is a cross-sectional viewfon the line 6 6 of Figure 1.

Figure 7 is a detail perspective view of one of the guide yokes, and

Figs. 8 and 9 .are detail elevations ofthe guide members detached.

Referring more particularly to the drawingsthe letter A designates aportion ofthe frame of a sawmill and B designates a buzzsaw mountedthereon andv driven inthe usual manner. Unnecessary produced details ofthe ordinary saw-mill mechanism are not disclosed as they are notessential to a proper understanding of the present invention.

In carryingout my invention Iprovide a vbase plate 10 which is mountedYupon the frame A and which is braced by a plurality of inclined bracebars 11 suitablyL bolted to the frame A and to the plate 10. Disposedupon the plate 1Q in spacedparallel relation and extendinglongitudinally of Athe plate, that is parallel withl the saw B, aresimilar A.yokes 12 which have their intermediate por- .tions olf-setupwardly as shownat 13 and place his hands anywhere near the rapidly*Awhich have their end, po-rtions constituting bearing feet 14 restingrupon theplate 10.

VThe portions 14 are formed with elongated slots 15 through which passbolts 16 passmg into the plate 10 and which are for the vpurpose ofsecuring the yokes 12 adjustably in position. Disposedl uponthe plate-10Vand located beneath the upwardly oH-set portions 13 of the yoke 12 is aplate 17 which is a species of filler-plates and which eX-v I tendslaterally beyond the right hand yoke 12 as shown. The upwardly .off-setportions 13 of the yokes 12' are formedV with elongated slots 18 throughwhich pass bolts 19 screwed through the plate 17 whereby to hold thelatter in positionv and whereby-the yokes'may be adjustablymountedwithrespectto the plate 17. f.

Slidably 'mounted through the upwardly v olf-set vportions 13 of theyokes', at one end thereof, is a bar 20 which has one Vend carrying aguide pin l21 disposed in` slightly spaced relation to one side of thesaw B. This .bar 2O is disposed between oneedge of` the plate 17 and theadjacent vertical portions olf the yokes l2 as clearly shown.lncidentally this bar 20 is adjustable longitudinally whereby to varythe distancebetween the guide pin 2l and the saw. The outer guide membercomprises an L-shaped bar 22 which is slidably mounted between 'theother edge of the pl'atelf( and the adjacent vertical portions ot theyolres as clearly shown, the shorter arm ot this lf shaped bar 22carrying a guide pin ail disposed yin alignment with the pin 2i but atthe opposite side ot the saw blade. The bar 22 is likewiselongitudinally adjustable within the yokes whereby to vvary the distancebetween the pin 23 andthe saw. y y

In order to effect movement ot the guide bar 20, Iprovide a lever 24which is pivoted at 25 upon the plate 17 and which has one end elongatedto constitute a handle 25 and which has its other end 'formed withan'elongated slot 27 through `which passes a bolt 2S screwed into thebar 20. By shifting the lever 26 back and torth'it'will be readilyapparent that the bar 2O may be moved longitudinally.

I also provide a lever 29 which is pivoted by a bolt 33 upon the plate1T and which has one endelongatedto form a handle 3l. This lever has itsintern'iediate portion formed with an elongated lslot32 through whichpasses a bolt 30 screwed into the bar 22 at one end 'of the latter. Byshitting the lever 29 'back vand forth it will be readily apparent thatthe guide br'ar 22 may be shifted longitudinally for varying thedista'nce between 'the pin 23 and the saw B.

In order to provide means Jroi' holding the guide bars at their desiredadjusted position, l'makejuse of a. transversely disposed bear` ingmember Se lwhich is suitably bolted to the frame A and which carries abearing 35 through which "is rotatably mounted the smooth portion 36 ofa screw 3T which is threaded through a block 38 secured upon theplate'lO, with the free end of Ithis screw engaging the rear tace 'otthe guide bar 22.

The screw 87 has its opposite end formed with a squared portion 39adapted for engagement by a suitable wrench whereby the screw may berotated. Wlhen the screw is rotated in a cross-wise direction, it willbe quite readily apparent that the screw 3"( will have itsfree lend bearirmly'and strongly against the rear edge ot the guide bar whereby toforce the latter into engagement with the rearedge ot' the plate i? soas to hold the parts locked.

Inthe operation of the device it will be readily apparent that when theoccasion 'arises7 the operator may quickly and easily the levers, one orboth, 2li and 29 whereby to move the guide bars 2l) or as the case maybe so as to bring the guide pins 2l and 23 into thedesired position withrespect to the saw blade l5. W hen the proper adjust ment has beeneti'ected, it is merely necessary that the operator turn up the screw 3Twhereby to the member 22 and prevent movement ol' the parts. It will beapparent that owing to the provision ot the longitu` dinal slots withinthe yolres l2 that ample adjustment may be made so that the guide pins2l and 23 may be broughtinto proper relation to a saw regardless of thediameter thereof.

F rom the foregoing description and a study olf the drawings it will bereadily apparent that I have thus provided a simply constructed andconsequently inexpensive saw-guide for use in connection with buzzsawswhereby the proper adjustment may be 'effected without' it beingvnecessary for the operator to place his hand anywhere near the saw, thedevice being` consequently very' safe in operation and being in other.'respects highly efficient so that it will effectually` perform all the-functions vfor which it is in` tended.

'l/Vhile I have shown and vdescribed theA Acorresponding ends, a iillerplate secured to the said yoke. and located between the said bars,levers for adjusting the said bars, and screw operated' meansfor'inoving one ot the said bars against the'said filler plate t0 holdthe parts against movement. I

; 2. A saw guide comprising a base plate,

a pair or" longitudinally adjustable guidel yokes mounted thereon inspaced parallel relation to each other, a liller plate disposedcrosswise of the said yolres and adjustably connected to the latter formovement longitudinally thereof, said plate having its longitudinaledges spaced inwardly from the adjacent portions ot the said yokes to'denne a guide-way along each longitudinal edge of the said plate, aslide bar disposed 1n each guide-way, said bars having' corre 'spendingends provided with pins for engaging a'saw therebetween, a pair ofindependent-ly movable levers pivoted tofsaidller plate and respectivelyconnected with a slide bar, and means for exerting a lateral thrust onsaid bars and plate whereby the llO 5 base plate, :L peur .latter yokes.v

3. A saw guide comprising a base platte, a pair of spaced parallel yokessecured to folle may be clamped against the smid bars, means-foradjusting the bars transversely of the Said yoke, and clamping i nadjusted movable against one of the bau-s for exerting a lateralthrust'tbereon whereby the Seid bars and ller plate may be forced intobinding engagement With each other.
